sungwon Posted August 30, 2023 Report Share Posted August 30, 2023 hello This time, I installed g4x xtremex on Nissan Skyline ECR33. The special thing is that it has been converted to an r35 coil and was previously mapped to Apexi Power FC. Currently, RPM cut operates around 6500rpm. I also set the trigger offset to -85 and changed the dwell time, but the RPM cut remains the same. I attached the map file. Any advice would be appreciated. Thank you again 20230830_ecr33_dyno_trig.pclx Quote Link to comment Share on other sites More sharing options...
DerekAE86 Posted August 30, 2023 Report Share Posted August 30, 2023 Do you have a log of when it's hitting cut? Quote Link to comment Share on other sites More sharing options...

When I saw it, it went from 6500 rpm to 0 rpm and then back to 6500, similar to an ignition cut. I wonder if this is a CAS problem or a trigger or other settings problem. Thank you very much for your interest in this matter. Quote Link to comment Share on other sites More sharing options...
DerekAE86 Posted August 30, 2023 Report Share Posted August 30, 2023 That does sound more like a trigger problem. Ignition cut decreases/stops spark to prevent RPM going any higher than it currently is. If your RPM signal just disappears completely when you reach high RPM that's because the ECU has lost the signal from the position sensor. I don't have any experience with the Opto sensor on these engines so unfortunately can't give you any hints other than when you have access to the car do a trigger scope as well - it might give some insight on the quality of the trigger signal.
